Problems solved by technology

The existing corn foliar fertilizer has a single component, most of which are trace element fertilizers, and the fertilizer liquid has a short wetting time on the leaves, the fertilizer droplets are not easy to penetrate into the leaves, the nutrient penetration rate is low, and the water droplets of the liquid fertilizer have poor adhesion to the leaves. Easy to slide off the blade surface, causing loss
Especially in windy and high temperature weather, spraying fertilizer will cause the fertilizer solution to dry quickly on the leaf surface, affecting the absorption and effect of nutrients

Abstract

The invention discloses a lodging-resistant, disease-resistant and growth-promoting leaf fertilizer for corn. The leaf fertilizer comprises components as follows: 160-240 g / L of iminodisuccinic acid, 200-300 g / L of potassium silicate, 60-100 g / L of calcium nitrate, 20-60 g / L of zinc sulfate heptahydrate, 10-30 g / L of boric acid, 20-50 g / L of agricultural streptomycin and 20-30 g / L of glycerol. Potassium, calcium, zinc, silicone and other elements are particularly added to the leaf fertilizer, the leaf fertilizer has high permeability for leaves of the corn, the leaves of the corn are wetted for a long time, few liquid fertilizers are lost, the utilization rate of nutrient elements is high, meanwhile, the leaf fertilizer has a sterilization function and can effectively prevent bacterial wilt, downy mildew, small and large leaf spot diseases, rust diseases and the like from infecting the corn.

Description

technical field [0001] The invention belongs to the technical field of agricultural fertilizers, and in particular relates to a lodging-resistant, disease-resistant and growth-promoting corn foliar fertilizer. Background technique [0002] Corn is one of the most important food crops in the world. Maize has to go through the emergence stage, three-leaf stage, jointing stage, bell mouth stage, heading stage, flowering stage and maturity stage in its whole life. It is a high-yielding crop that likes temperature, light and has a short growth period. Because corn plants are tall, have well-developed root systems, and have strong fertility absorption, they need a lot of various nutrients. Fertilization is one of the important measures to obtain high yield of corn, improve corn quality and reduce production cost. Normally, corn absorbs the most nitrogen during the whole growth period, followed by potassium and the least phosphorus. The period from the jointing stage to the head...
